Analogue outputs (X21)

General: Two programmable current outputs: 0 (4) … 20 mA, RLResolution: 0.1% (10 bit)

Inaccuracy: ±1% (Full scale range) at 25 °C (77 °F). Temperature coefficient: ±200 ppm/°C (±111 ppm/°F) max.

Digital inputs (X22)

General: Six programmable digital inputs (common ground: 24 VDC,

-15% … +20%) and a start interlock input (DIIL). Group isolated, can be divided into two isolated groups (see Isolation and grounding below).Thermistor input: 5 mA, < 1.5 kohm “1” (normal temperature), > 4 kohm “0” (high temperature), open circuit “0” (high temperature).

Internal supply for digital inputs (+24 VDC) is short-circuit proof. An external 24 VDC supply can be used instead of the internal supply.

Isolation test voltage: 500 VAC, 1 min

Logical thresholds: < 8 VDC “0”, > 12 VDC “1”

Input current: DI1 to DI5: 10 mA; DI6: 5 mA

Filtering time constant: 1 ms

24 VDC power output (X23)

Voltage: 24 VDC ±10%, short-circuit proof

Maximum output current: 250 mA (without any optional modules inserted)Relay outputs (X25, X26, X27)

General: Three programmable relay outputs

Switching capacity: 8 A at 24 VDC or 250 VAC; 0.4 A at 120 VDC

Minimum continuous current: 5 mA rms at 24 VDC

Maximum continuous current: 2 A rms

Isolation test voltage: 4 kVAC, 1 min

Slot 1 (X31)

General: For connection of I/O extension modules (such as RAIO and RDIO), pulse encoder interface (RTAC), or fieldbus adapters (such as RPBA and RMBA)Slot 2 (X32)

General: For connection of I/O extension modules (such as RAIO and RDIO) or pulse encoder interface (RTAC)

DDCS (X33)

General: For connection of RDCO-0x(C) DDCS Communication module
