The input terminal act as a counter has a limit over the maximum frequency. Any frequency higher than that may result in incorrect counting or abnormal system operation. Make sure that the input terminal arrangement is reasonable and external sensors used are proper.
The PLC provides an S/S terminal for selecting signal input mode among source mode and sink mode. Connecting the S/S terminal to the +24 terminal, i.e. set the input mode to the sink mode, enables a connection with the NPN sensor.

The following figure shows the terminal wiring: 
The labels 0 to 0 in the above figure indicate the connection that you need to pay special attention to.
- It is recommended that you connect the thermistor signals by using a shielded twisted-pair cable, and keep the cable away from power cables or other cables that may cause electrical interference. The connection of a thermistor is described as follows:
For thermistor sensors of the Pt100, Cu100, and Cu50 types, you can use the 2-wire, 3-wire, and 4-wire connection methods. Among them, the precision of the 4-wire connection method is the highest, that of the 3-wire connection method is the second highest, and that of the 2-wire connection method is the lowest. If the length of the wire is longer than 10 m, it is recommended that you use the 4-wire connection method to eliminate the resistance error caused by the wire.
To reduce measurement errors and prevent noise interference, it is recommended that you use connection cables that are shorter than 100 m. - If too much electrical interference is caused, connect the shielding ground to the ground terminal PG of the module.
- Ground the ground terminal PG of the module properly.
- Use 220Vac power supply. O. Short-circuit the positive and negative terminals that do not use a channel to prevent the detection of error data on the channel.
SD unit configuration
| Address No. | Name | RIW attribute | Note |
| SD172 | Sampling average of CH1 | R | Default value: 0 |
| SD173 | Sampling times of CH1 | RW | 1-1000, Default value: 8 |
| SD174 | Sampling average of CH2 | R | Default value: 0 |
| SD175 | Sampling times of CH2 | RW | 1-1000, Default value: 8 |
| SD178 | Mode selection for CH1 (8 LSBs) Mode selection for CH2 (8 MSBs) | RW | 0: Disable 1:PT100 (-1500-6000, degrees Celsius) 2:PT100 (-2380-11120, degrees Fahrenheit) 3:Cu100 (-300-1200, degrees Celsius) 4:Cu100 (-220-2480, degrees Fahrenheit) 5:Cu50 (-300-1200, degrees Celsius) 6:Cu50 (-220-2480, degrees Fahrenheit) |
Setting example:
In order to configure the PT100 for both CH1 and CH2, output the value in degrees Celsius, and set the points of average value to 4, you need to set the 8 leaset significant bits(LSBs) of SD178 to Ox01 and the 8 most significant bits(MSBs) of SD178 to Ox01, i.e. set the SD178 to Ox0101(hexadecimal). Then set the SD173 and SD175 to 4. The values of SD172 and SD174 are the average temperatures in Celsius degree of the four samplings detected by the CH1 PT100 and CH2 PT100, respectively.
Communication Port
IVC1L-1616MAR-T basic module has three serial asynchronous communication ports: PORTO, PORT1, and PORT2. Supported baud rates: 115200, 57600, 38400, 19200, 9600, 4800, 2400, 1200bps. The mode selection switch determines the communication protocol of PORTO.
| Pin No. | Name | Description |
| 3 | GND | Ground |
| 4 | RXD | Serial data receiving pin (from RS232 to PLC) |
| 5 | TX D | Serial data transmitting pin (from PLC to RS 232) |
| 1, 2, 6, 7,8 | Reserves | Undefined pin, leave it suspended |
As a terminal dedicated to user programming, PORTO can be converted to programming protocol through the mode selection switch. The relationship between PLC operation status and the protocol used by PORTO is shown in the following table.
| Mode selection switch position | Status | PORTO operation protocol |
| ON- | Run | Programming protocol, or Modbus protocol,or free-port protocol, or N: N network protocol, as determined by user program and system configuration |
| ON→TM | Running | Converted to programming protocol |
| OFF →TM | Stop | |
| OFF | Stop | If the system configuration of user program is free-port protocol, it converts to programming protocol automatically after stop; or system protocol keeps unchanged |
PORT1. PORT2 are ideal for connection with equipment that can communicate (such as inverters). With Modbus protocol or RS485 terminal free protocol, it can control multiple devices through the network. Its terminals are fixed with screws. You can use a shielded twisted-pair as the signal cable to connect communication ports by yourself.
Installation
PLC is applicable to Installation category II, Pollution degree 2.
5.1 Installation Dimensions
| Model | Length | Width | Height | Net weight |
| IVCAL-1616MAR-T | 182mm | 90mm | 71.2mm | 750g |
5.2 Installation Method
DIN rail installation
Generally you can install the PLC onto a 35mm-wide rail (DIN), as shown in the following figure. 
The detailed procedure is as follows:
- Fix the DIN rail onto the installation backplane;
- Pull out the DIN rail clip from the bottom of the module;
- Mount the module to the DIN.
- Press back the DIN rail clip to lock the module.
- Fix the two ends of the module with the rail stops to avoid sliding.
This procedure can be used to install the DIN rail for all other IVC1L-1616MAR-T PLCs.
Screw fixing
Fixing the PLC with screws can stand greater shock than DIN rail mounting.
Use M3 screws through the mounting holes on PLC enclosure to fix the PLC onto the backboard of the electric cabinet, as shown in the following figure. 
5.3 Cable Connection and Specification
Connect power cable and grounding cable. We suggest you wire a protection circuit at the power supply input terminal. The following figure shows shows the connection of the AC and auxiliary power supplies.
The anti-electromagnetic interference capability of the PLCs can be improved by configuring reliable grounding cables. When installing a PLC, connect the power supply terminal 
to the ground. It is recommended that you use connection wires of AWG12 to AWG16 and try to shorten the wires, and that you configure independent grounding and keep the grounding cables away from those of other devices (especially those generating strong interference), as shown in the following figure.
Cable specification
When wiring a PLC, use multi-strand copper wire and ready-made insulated terminals to ensure the quality. The recommended model and the cross-sectional area of the cable are shown in the following table.
| Cable | Cross-sectional area | Recommended model | Cable lug and heat-shrink tube |
| AC power cable (L, N) | 1.0-2.0mm2 | AWG12, 18 | H1.5/14 round insulated lug, or tinned cable lug |
| Earth cable (e) | 2.0mm2 | AWG12 | H2.0114 round insulated lug, or tinned cable lug |
| Input signal cable (X) | 0.8-1.0mm2 | AWG18, 20 | UT1-3 or OT1-3 solderless lug 1)3 or c1314 heat shrinkable tube |
| Output signal cable (Y) | 0.8-1.0mm2 | AWG18, 20 |
Fix the prepared cable head onto the PLC terminals with screws. Fastening torque: 0.5-0.8Nm.
The recommended cable processing-method is shown in the following figure.
