Module Installation/Disassembly
Installation
- With the front of the relay output module facing you, press the module down with the signal input ports against the upper side of the DIN rail.
- Press the module down and the plastic clamp will slide. Continue to push down until the plastic clamp “clicks”.
Removal
- Use a screwdriver to pull the plastic clamp sideways and detach the module from the DIN rail.
- Remove the relay output module from the DIN rail in reverse order of installation.

Relay Output Module Control Register Description
Relay Output Module Register Communication Method
Use Modbus RTU/ASCII to write in single-chip relay output module registers The address for the relay output module register to be written is: 0x2000
※With no control module, RS485’s physical wire must be connected with an adapter to send the signal to the power and relay output module
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | |
| Adapter BS-211 | 24V | 0V | 5V | 0V | 485A | ─ | 485B | ─ |
| Terminal block 0181-A106 | 24V | 0V | 5VDC | 0V | 485A | 485B |
Use Modbus RTU/ASCII with control modules to write in relay output registers
Once a relay output module is set up with a control module, it will automatically assign the relay output
modules’ output records registers at the address of 0x2000
Example:
Two relay output module registers will be between 0x2000 and 0x2001
※When using control modules, RS485 can connect to control modules with BS-210 and BS-211
The configuration that uses Modbus RTU/ASCII with a control module to write in relay output modules is listed below:
| Name/Product No. | Description |
| GFMS-RM01S | Master Modbus RTU, 1 Port |
