OUTPUT DEVICES

OUTPUT DEVICES

Two of the following output devices are fitted to the controllers, depending on the model.

1Solid state relay drive (SSd/SSd1/SSd2) 5Vdc +0/-15%, 15mA non isolating

To switch a remote SSR (or logic)

2Miniature power relay (rLY/rLY1) 2A/250V resistive, Form A/SPST contacts.

3Sub miniature power relay (rLY2) 1A/250V resistive, Form A/SPST contacts.

OUTPUT DEVICE ALLOCATION

Either of the available outputs may be chosen for the main setpoint (SP1), the remaining device being automatically allocated to the second setpoint (SP2).

See example illustrated on page 30.

STANDARD MODEL CN9412

Output Device 1 + Output Device 2

DUAL RELAY MODEL CN9411

Output Device 2 + Output Device 3

DUAL SSd MODEL CN9422

Output Device 1 + Output Device 1

Dual relay or dual SSd model options CN9411 / CN9422 are fully detailed on page 22.

ELECTRICAL INSTALLATION

Designed for use with the following supply voltages:

100 - 240V 50-60 Hz 4.0 VA (nominal) +/-10% maximum permitted fluctuation

12V - 24V (AC/DC) +/-20% 4.5 VA Polarity not required

WIRING THE CONNECTOR

Prepare the cable carefully, remove a maximum of 8mm insulation and ideally tin to avoid bridging. Prevent excessive cable strain. Maximum recommended wire size: 32/0.2mm 1.0mm2 (18AWG).

INDUCTIVE LOADS

To prolong relay contact life and suppress interference it is recommended engineering practice to fit a snubber (0.1uf/100 ohms), refer to illustration on page 30.

CAUTION:

Snubber leakage current can cause some electro-mechanical devices to be held ON. Check with the manufacturers specifications.
