Output Modules
4.3.1
mA output module (four-way)
The mA output module has four potential-separated mA outputs.
Each output can be configured in the menu to 0–5 mA, 0–10 mA,
0–20 mA or 4–20 mA. Any measured value, actuator output Y
out
or temperature can be assigned to the mA outputs.
Please note
The maximum load of each mA output can be switched over for
thermal reasons. If less than 400 Ohm load is connected, the
corresponding mA output's bridge should be attached to L (load
< 400 Ohm). At higher loads, (max. 1000 Ohm), the bridge must
be attached to H (load up to 1000 Ohm).
4.3.2
Relay Module (eight-way)
The relay module has over eight relays, each with a two-way
switch. These switches are assigned various switching tasks
depending on the selected application (see 4.4 “Applications" on
page 71). The corresponding diagrams for the five applications are
in the appendix under 9. “Wiring Diagrams" on page 245. The
switches are wired with suppressor diodes to protect from spikes.
In order to switch larger inductive load, we recommend installing
an additional contact such as a contactor or load relay, in order to
guarantee the contacts have a longer service life.
