Analog outputs (66, 68, 70): Output voltage range 0…10 V. Output current max. 10 mA / output
15 VDC output (1): 15 VDC output maximum load 100 mA
24 VAC output (51): Total current of 24 VAC output and triac-outputs max. 1A.
Pump control contacts (81-89): Contacts for three circulation pump. Pumps are controlled by a switches on the top of the H23 device. Relay max. load 3A.
Protective earth terminal (73-78): Protective earth terminal block for 230V devices. Control circuit fuse max. 10A
Control outputs (51): 24 VAC -control output
– Triac (55…60): Total current of triac-outputs and 24 VAC output max. 1A.
Data transfer connections
– RS-485-bus A (3) and B (6): Unisolated, supported protocols Modbus-RTU
