1.3.5Linear Inputs

For linear mA input ranges, connection is made to Terminals 4 and 6 in the polarity shown in Figure 1-4. For linear mV and V ranges, connection is made to Terminals 4 and 5 in the polarity shown in Figure 1-4. For details of the linear input ranges available, refer to Appendix A.

1.3.6Remote Run/Hold Input

With this option fitted, Terminals 11 and 12 are used for external Run/Hold control of the currently-selected program; this has an effect identical to that of the front panel RUN key. These terminals may be connected to (a) the voltage-free contacts of a switch or relay, or (b) a TTL-compatible voltage. This is an edge-sensitive input for which the following convention has been adopted:

For TTL input, OFF = logic 1 and ON = logic 0

For a voltage-free input, OFF = open and ON = closed

Program control is as follows:
OFF-ON transition:	The currently-selected program will run (or
	will resume running if it is currently held).
ON-OFF transition:	The currently-running program will be
	held.

NOTE: When this input is used, the front panel RUN key can be used only to abort a program. Powering-up the Profile Controller whilst this input is ON will not cause a program to run. The RS485 Serial Communications option and the Remote Run/Hold option are mutually exclusive.

1.3.7Relay Outputs

The contacts are rated at 2A resistive at 120/240V AC.

1.3.8SSR Drive Outputs

These outputs produce a time-proportioned non-isolated DC signal (0 - 4.2V nominal into 1k minimum).

1.3.9Solid State Outputs

These outputs provide up to 1A AC drive with a longer lifetime than an electromechanical relay. For further details, refer to Appendix A.
