Technical data of ST501-LN1KV.04
Inputs
E1:
extern potential-free switching input for pump failure, closed at failure
E2:
extern potential-free switching input for high pressure alarm, opened at alarm
E3:
extern potential-free switching input for low pressure alarm, opened at alarm
E4:
extern potential-free switching input for ventilator failure, opened at failure
Measuring input
A99 = 0, operation as standard temperature controller:
F1:
Resistance thermometer PTC, actual value
F2:
input inactive
A99 = 1, operation as differential temperature controller:
F1:
Resistance thermometer PTC, following value
F2:
Resistance thermometer PTC, leading value
Measuring range for PTC (KTY81-121): -50 ...+130 °C
Accuracy: ±0.5 K ± 0.5 % at 25 °C
Display
One 3-digit LED-Display, height 13 mm, colour red.
Ten LEDs for status display of the outputs K1, K2 und K3, the constant value control, the generic
alarm and the digital inputs E1, E2, E3 and E4.
Outputs
K1:
Relay 8(1.5) A normally-open contact, connected to power supply 12-24 V
K2:
Relay 8(1.5) A normally-open contact, connected to power supply 12-24 V
K3:
Relay 8(1.5) A normally-open contact, connected to power supply 12-24 V
K4:
Relay 250 V~, 8(1.5) A change-over contact, galvanically separated
Relay K2 is in series with input E2 and thus is interrupted by high pressure alarm.
