3.1. Power Supply
The units require a DC supply from 17 to 30 volts which must be applied to terminals 1 and 2.
Depending on the input voltage level and internal states, the power consumption may vary and
lies in a range of about 70 mA with a 24 volts input (plus encoder currents taken from the
auxiliary voltage output).
3.2. Auxiliary Output for Encoder Supply
Terminals 4 and 3 provide a +5.2 VDC / 200 mA auxiliary output for supply of encoders and
sensors.
3.3. Inputs for SinCos Encoders and Sensors
The encoder shall be connected at the screw-type terminal 5-8 of the device. Only encoders
with differential sine-cosine signals of 1 Vpp can be used (0.8 Vpp - 1.2 Vpp). At any time the
signals sin+/sin- and cos+/cos- must be available.
Pins 3 (GND) and 4 (+5,2 V) of the screw-type terminal provide an auxiliary power output for the
encoder supply.
3.4. Control Inputs
Two programmable control inputs allow the assignment of functions like remote start-up-delay,
reset of relay lock, hardware interlock of the keypad and similar.
Both inputs provide PNP characteristics and require HTL level. Also it is possible to set the
control function to "active LOW" or "active HIGH".
For evaluation of dynamic events the desired "active edge" can be set (rising or falling edge)
