== Solid State Relay Output Module (WBIO-DO-SSR-8) ==
Purpose
Designed for control of low-voltage load, devices with inputs for "dry contacts". Devices may not have common ground with the controller.
Specifications
The module contains 8 independent channels of optorele SPST configuration (normally open).
Each channel has built-in protection against voltage surges when switching inductive load (TVS for 30V).
Parameter | Value |
---|---|
Number of outputs | 8 |
Output type | optorele |
Contact configuration | SPST (normally open) |
Maximum switching voltage | 30 V AC and DC |
Maximum switching current, per channel | 400 mA |
The channel resistance in the open state | < 2 Ohms |
Voltage isolation between the controller and the output | 1500 V (RMS) |
Module type | "O" (non-inverted address scheme) |
Maximum power consumption | 0.2 W |
Width, DIN units | 2 |
Size | 36,3x90,2x57,5 mm |
Terminals and wire section | |
---|---|
Recommended wire cross-section with TSVI, mm2 | 0,75 — 1 |
Length of the standard sleeve NSVE, mm | 8 (10 for adjusting screwless terminal blocks) |
Torque of screws, N∙m | 0,2 (for screw terminals) |
Connection to controller
See activating the module in the web interface of the controller. The relay will be presented by the controls of EXTx_K1 — EXTx_K8 of the Discrete I/O device in the web interface. The corresponding MQTT-topics: /devices/wb-gpio/controls/EXTx_Ky.
Load connection
Each pair of outputs is galvanically isolated from the others. No polarity.
