Output Modules
The Athena 6050 offers users 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 resistive heaters.
NOTE: Do not use this output module with mechanical contactors because they generate an excessive EM1 field which can interfere the 6050's microprocessor. Instead we recommend "T" output modules for this application.
Module Type F: This
A
return for ground currents of the milliamp source. It is connected internally to the mating lug on the heat sink. To avoid ground loops, drive floating (ungrounded) loads or use isolated thermocouples.
Module Type T: This solid state relay is capable of 1 AM? at 120/240 Vac. It is zero voltage switched and optically isolated from the drive signal. With it, resistive loads up to 120 watts at
at 120 Vac and 240 watts at 240 Vac may be controlled directly. Using direct control there is no lower limit on the cycle time setting (down to 60 milliseconds). Larger loads may be controlled utilizing an external contactor. In this case, it is advisable to use cycle settings of ten seconds or greater to minimize contactor wear. External suppression of the contactor is mandatory.
Module Type S: Similar to F, but pulsed 2OV/2OmA DC 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 without sacrificing S.S.R. life.
