What's new in version 2.1:

- memory life increased up to 100 trillion events counter and 151-year data retention because of FRAM (ferromagnetic memory) usage to store counters' values;

- full galvanic isolation of RS485 line;

- over-voltage and over-current protection of RS485 line;

- full optical isolation of inputs;

- updated circuitry and firmware.

Description:

Modbus RTU operated module with 8 relays, 8 opto-isolated inputs and 2 counters (counters for 1-st and 2-nd inputs).

Size: standard DIN rail 157 mm wide enclosure (157x110(including connectors)x56 mm).

Commands: standart Modbus RTU commands read relay state, change relay state, read input state, read input counters value, change port baudrate, set module address, clear counters.

Indication: 8 relay state LED, 1 power on LED.

Maximal output load: 7A 250VAC / 15A 120VAC / 10A 30VDC.

Power supply: 12V 400mA.

Power consumption: stanby - 90 mA, all relays activated - 370 mA.

Inputs: 8 opto-isolated discrete inputs (input voltage 3.3 ... 24V).

Counters: 2 counters of input events (for 2 inputs only).

Memory: non-volatile memory chip for settings and counters.

Connection: screw connectors.

Modbus address: (can be changed by Modbus command) 0...255 (default address: 0x01).

Baudrate: (can be changed by Modbus command) 2400, 4800, 9600, 19200, 28800, 38400, 56000, 57600, 115200, 128000, 256000 (default is 9600).

Port settings: 8n1

Manual and testing software: will be sent along with the module.
