8.3.2 Input Terminals
8.3.2.1 Set-Value
Terminals 1 through 3 are used to receive a parameterisable modulating set-value for control operation within the
range of 0-20 mA or 0-10V.
8.3.2.2 Sensor Feedback for Process Controller (optional)
Terminals 15 through 17 (main board) resp. 10 through 12 (terminal box) are used to receive a process sensor‘s
feedback to the - optional - process controller, in the parameterisable range of 0-20 mA or 0-10 V.
Caution!
The following binary input terminals (8.3.2.3 & 8.3.2.4) have priority over the
modulating set-value. If the actuator is parameterised for modulating service,
these set-value settings are disregarded in case a binary signal is applied. Only after
disconnection of the binary signal the actuator will reposition according to the set-
value applied.
8.3.2.3 Binary Input
Terminals 9 through 11 (main board) resp. 17 through 19 (terminal box) are for binary open/close signals. Standard
voltage level is 24 V to 230 V; see wiring diagram. The actuator is then driven in 3-point service.
8.3.2.4 Fail-safe port for Binary Input (optional)
The fail-safe port of the terminals 12 and 13 (main board) resp. 25 and 26 (terminal box) allows to drive the actuator
to a parameterised safety position by applying a voltage of 24 V to 230 V.
8.3.3 Output Terminals
8.3.3.1 Active Position Feedback
Active position feedback is adjustable within the range of 0-20 mA or 0-10 V.
Main board: terminals 4 - 6
Terminal box: terminals 4 - 6
8.3.3.2 Additional Position Switches (optional)
The activation points of the optional position switches can be mechanically adjusted via two cams. The switches can
be accessed as potential-free changeover contacts. The standard switches with silver contacts are rated to 230
VAC/5 A. Special switches with gold plated contacts for low power (up to 100 mA and 30V) are available on request.
Limit switch board: terminals X6 / 1-3 or X6 / 4-6 respectively
Terminal box: terminals 22/27/28 or 23/29/30 respectively
8.3.3.3 Voltage Feed to Process Sensor (optional)
Terminals 14 and 17 provide an unregulated output voltage of 21 to 40 VDC at maximum 100 mA to feed an external
process sensor.
Main board: terminals 14 + 17
Terminal box: terminals 9 + 12
8.3.3.4 Fault Indication Relay (optional)
This potential-free relay contact allows to display adjustable fault indication to the control room with a maximum
load of 24 VDC/100 mA. See instruction manual for software PSCS.
