IQTB-TC840
Ethernet temperature and humidity controller board with two sensor inputs, two relays and SNMP.
IQTB-TC840 — Ethernet temperature and humidity controller board with two sensor inputs, two relays and SNMP.
IQTB-TC840 IQboard LAN: Ethernet temperature and humidity monitor, IP thermostat and hygrostat with two sensor inputs, two 1 A relays, data logging and SNMP.
IQTB-TC840 is an IQboard LAN controller for monitoring temperature and humidity and controlling equipment over Ethernet. Connect compatible external sensors to its two inputs, view current readings and recorded history in a web browser, and use two relay outputs for thermostat, hygrostat or scheduled control. The board supports SNMP monitoring and traps, differential control and an equithermal control table. Passive PoE and an optional DIN-rail adapter simplify installation. The relay contacts are rated 30 V DC / 1 A; they are not intended to switch mains loads directly. Production has ended; the original English manual remains available for installed units.
