positive is connected to terminal A1. The relay release time increases insignificantly.Green LED moduleLED modules are used for AC and DC. The LED indicator lights up when the coil is energized. When using DC it is essential that positive is connected to terminal A1.Diode module (non-standard polarity)Recovery diode modules are used for DC only. The reverse voltagepeaks of the coil are short circuited by the recovery diode (positive to terminal A2).The release time increases by an approximate factor of 3.If an increase of the release time is undesirable use a Varistor or RC module.RC moduleRC circuit modules are used for AC and DC coils. The reverse voltage peaksof the coil are limited by the RC module to approximately 2.5 times thenominal voltage of the supply. The relay release time increases insignificantly.Residual current bypass moduleBypass modules are advisable if 110 or 230v AC relays show any tendency to fail to release. Failure to release can be caused by residual currents from AC proximityswitches or inductive coupling caused through long parallel lying AC control lines.99 Series - Coil indication and EMC suppression modules99.01.9.xxx.79 only99.80.9.xxx.79 only99.02.9.xxx.79 only99.01.2.000.00 only99.80.2.000.00 only99.02.2.000.00 only
