Digital outputs / relay
outputs
 DO 0: Relay output, 30 V DC / max. 0.5 A with resistive load
 DO 1: Transistor output, 30 V DC / max. 0.5 A with resistive load, protection against
incorrect voltage polarity
 DO 2: Relay output, 30 V DC / max. 0.5 A with resistive load
Update time of all DO: 2 ms
For applications, which require UL certification, the voltage at DO 0 must not exceed 30 V DC
referred to ground potential and must be supplied via a grounded class 2 power supply.
Analog outputs AO 0, AO 1: 0 V … 10 V or 0 mA … 20 mA, reference potential: "GND", resolution 16 bit,
update time: 4 ms
Temperature sensor
 PTC: Short-circuit monitoring 22 Ω, switching threshold 1650 Ω
 KTY84
 ThermoClick sensor with dry contact
Fail-safe digital input
(Basic Safety)
 DI4 and DI5 form a fail-safe digital input
 Maximum input voltage 30 V, 5.5 mA
 Response time:
– Typical: 5 ms + debounce time p9651 (6 ms, if p9651 = 0)
– Worst-case scenario: 15 ms + debounce time p9651 (16 ms, if p9651 = 0)
