Модуль 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.
