1.6Electrical I/O Connections

1.6.1Analog Output

The analog output is a two pin connector (See Figure 1.4). The analog output can be configured for voltage or current output. The standard is a 0-5 volt output. 0-100mV, 0- 1V, 0-10V, and 4-20 mA outputs are also available. See Section 5.2 for information on setting other output ranges.

1.6.2 Relay Outputs

Three form C relay outputs are provided on three pin connectors (See Figure 1.1). These outputs correspond to the ‘HI’ and ‘HI-HI’ concentration alarms and a System OK status output that is used to indicate a fault or error condition in the instrument. The relay contacts are rated to 3A at 240VAC. Do not exceed these ratings when connecting equipment to the instrument.

1.6.3 Digital Outputs

There are 12 digital output. These outputs are optically isolated NPN transistors which can pass 50 mA of DC current. These outputs can be used to interface to devices that accept logic-level digital inputs, such as Programmable Logic Controllers(PLC’s).

The outputs labeled ‘STATUS OUT’ are used to indicate instrument operational status and fault conditions. Table 1.1 below summarizes the functions of all the digital outputs.
