Digital temperature switch 2 thresholds for explosive atmosphere • Digital temperature switch 2 independent thresholds • For PT100 installed in zone G or D • Outputs 2 form C relays • Device ATEX category II (1) GD • Configuration via USB plug • DIN 22mm rail mounting
The digital temperature switch PROFSI2-APT….2A allows the wiring of a PT100 temperature probe installed in hazardous area – zone 0, 1, 2 or 20, 21, 22- and the activation of 2 independent thresholds. The outputs are 2 form C (SPDT) relays. Relays status are configurable. The digital temperature switch configuration is done through an USB plug on a PC. The configuration software is delivered with the device; it is also available on our website. This kind of configuration ensures the threshold locking on. The digital temperature switch PROFSI2-APT….2A is powered from 24V to 250V AC or DC. It is housed in a DIN rail-mounting module, width on rail 22mm.
