DESCRIPTION AND TECHNICAL DATA
DESCRIPTION
Temperature controller for heating applications such as
heating cables in industrial plants, with additional alarm relay.
Design for DIN rail mounting. Temperature sensor Pt100 in
3- or 2-wire technology, thermocouples type J, thermocouple
type K or standard signals (0/2V - 10V, 0/4mA - 20mA). Many
different control functions.
Operating status LEDs
LED 1 = operation (heating on)
LED 2 = ramp mode
LED 3 = signaling relay (alarm 2)
LED 4 = alarm relay (alarm 1)
Soft start
When using the internal hybrid relay as a switching output, a
soft start phase is initiated for 20 seconds before each cold start
of the load relay (with 14% power via triac output) in order to
reduce the starting current.
Digital inputs
DigIn1 is used with structure switch position S07 – 2 (external
controller release) and serves as an external release of the load
output.
DigIn2 is used with the structure switch position S04 - 5 (limiter
function) and serves as an external unlocking.
DigIn3 is used with structure switch position S03 – 6 (W1/W2
switchover) and is used to switch between W1 and W2.
