2.4 Electrical I/O Connections

All user I/O connections are available on the 16 pin connector on the mainboard (See Figure 2-3 for location.) This connector can be unplugged from the header on the mainboard for easier access when wiring. To disconnect from mainboard, loosen the two retaining screws at either end of the connector.

When connecting multi-strand wire to this connector, the wire ends should be “tinned” with solder to ensure a reliable connection. This is not necessary if solid-core wire is used.

2.4.1 Analog Output

The analog output is located on the two pins labeled ‘Analog Out +’ and ‘Analog Out –‘ The analog output can be configured for voltage or current output. The standard output is a 0-5 volt output. The analog output can also be optionally configured for a 4-20mA Current output. Check the serial number tag on the instrument to determine Analog Output configuration.
