Facilitating the safe control of intrinsically safe valves in hazardous environments, the Weidmuller 8965420000 (ACT20X-2SDI-2HDO-S) provides reliable signal isolation and switching. This dual-channel valve control module acts as an isolated barrier, translating control signals from the safe area into intrinsically safe outputs to drive solenoids, valves, and acoustic alarms located in Ex zones.

The ACT20X-2SDI-2HDO-S is highly compatible with standard DCS and PLC digital output cards. When integrating this module into existing systems configured with older ACT20 series units, ensure that the FDT/DTM frame application is updated to the latest device description files to prevent communication errors during setup.
When mounting multiple units side-by-side on a DIN rail, ensure the cabinet's thermal management system is active. Under maximum continuous current loads (0.5 A AC / 0.3 A DC), heat dissipation within high-density enclosures can rise. Maintain a minimum clearance or use active ventilation if the ambient temperature inside the panel consistently exceeds 45 degC.
Always maintain strict physical separation between the blue intrinsically safe (Ex-i) field wiring and the non-intrinsically safe supply/alarm connections. Mixing these routing paths violates hazardous area compliance. Use shielded cabling for the control signals to minimize high-frequency noise interference in high-transient environments.
CRITICAL WARNING
Isolate and de-energize all power sources before mounting, wiring, or configuring this module. Ensure the surrounding atmosphere is verified as non-hazardous (gas-free) before opening any protective enclosures or adjusting field connections.
Snap the module securely onto a standard TS 35 DIN rail, ensuring the grounding spring makes solid contact with the rail.
Connect the 19.2 to 31.2 V DC power supply to the designated non-Ex power terminals.
Wire the intrinsically safe valve/solenoid field devices to the blue Ex-i screw terminals, keeping the cables physically isolated from power lines.
Connect the alarm relay outputs to your supervisory PLC or safety system to monitor for voltage loss or device faults.
