SECTION 3 OUTPUT MODULES
3.1
Module Description
The Athena 6075 offers field interchangeable output modules. This unique
feature makes it possible to fill output requirements for a variety of
applications with a single controller model.
Module Type B: This 7A/5A relay (at 120/240 Vac) is used for driving resis-
tive heaters.
N O T E :
Do not use this output module with mechanical contactors
because they generate an excessive EMI field which can interfere
with the 6075’s microprocessor, Instead, we recommend “T’
output modules for this application
Module Type F: This 4-20
mA
output module can deliver full output to loads
having an input impedance of 500 Ohms or less. The cycle time setting
must be ZERO for smooth current output.
Module Type S: Similar to F. but pulsed 20 Vdc output for driving solid state
relays. Up to 6 (input series connected) solid state relays can be used. Cycle
time can be set to optimize the load response time requirements.
“F’ & “S” M O D U L E NOTE:
A push-on terminal is utilized as a return for ground currents of
the milliamp source. I t is connected internally by the mating lug
on the circuit board. To avoid ground loops, drive floating
(ungrounded) loads.
Module Type T: This solid state relay is capable of 1 amp at 120/240 Vac. It is
zero voltage switched and optically isolated from the drive signal. With it
resistive loads up to I20 watts at I20 Vac and 240 watts at 240 Vac may be
