Control outputs
Control output 1
3 different versions are possible
Relay contact
Loading: AC 250 V, 3 A (resistive load), AC 250 V, 1 A (inductive load,
cos ϕ = 0.4)
Logic level
DC 0/12 V, max. 40 mA (short-circuit proof)
for the control of an electronic switch relay (solid-state relay, SSR)
{analogue current signal}
4 ... 20 mA, max. load 550 Ω
Control output 2
1)
For “three-step control”
Output
Contact-free relay, loading: AC 230 V, 0.3 A (resistive load)
Proportional band
0.0 to 10.0 times the proportional band of control output 1
Integral time
Identical to the integral time of control output 1 (see “Control Mode”)
Derivative time
Identical to the derivative time of control output 1 (see “Control Mode”)
Cycle time
1 ... 120 s
Overlap band/deadband
Resistance thermometers and thermocouples: -100.0 ... 100.0 °C
Standard signals: -1,000 ... 1,000 (with a scaling of the input with one
decimal point, this is taken over by the hysteresis).
{ } Items in curved brackets are optional extras for an additional price
1) A combination of alarm output 2 or heater burnout alarm with relay output 2 is not possible.
