As standard the TOC-625 controller is equipped with two relay outputs. The function of these two relay
outputs can be user configured and is discussed in a later section. The relays are rated to operate 4A
non inductive loads. Typical wiring arrangements are indicated below and show typical methods to
protect the relays during installation.

As standard the TOC-625 is equipped with three analogue outputs. By default these are configured
as 4-20mA current outputs. By request these can be set to 0-10V DC outputs during production. This
is a factory only setting. The following diagrams indicate the connections

Note this diagram shows the use of screened
cabling when interfacing signal cables. Signal
cables should be segregated from power and
control cables for best results.
