Helios Large Display Pulse Input Rate/Totalizer Instruction Manual

Signal Connections

Signal connections are made to a six-terminal connector labeled SIGNAL on Figure 7. The COM

(common) terminal is the return for the input signals.
The following figures show examples of signal connections.
Setup and programming is performed through the front panel buttons.

Modbus RTU Serial Communications

Serial communications connection can be made to the onboard RS485 terminal block or USB connector

shown in Figure 7. If RS232 is required, an RS485 to RS232 adapter (PDA7485) may be used. See

Ordering Information on page 5 for additional information.

Relay Connections

Relay connections are made to two six-

terminal connectors labeled

RELAY1 – RELAY4 on Figure 7. Each

relay’s C terminal is common only to the

normally open (NO) and normally closed

(NC) contacts of the corresponding relay.

The relays’ C terminals should not be

confused with the COM (common)

terminal of the INPUT SIGNAL connector.
