Libertas 3700 series modular relay and high current switching panels provide consistent ringing with accurate pulse timing. | |||
== Technical description == | |||
From left to right, each panel includes the following modules | |||
* Interface Module | |||
* Power Supply Module | |||
* Output Module(s) | |||
** DC Striker T4 - four DC striker outputs | |||
** Combination Output - one DC striker and three motor control dry contact relays | |||
** Relay Module M4 - four dry contact relays, typically used for motor control | |||
The modules are tied together using a ribbon cable that carries power, control voltages and logic signals. Additionally high voltage DC jumpers feed 200VDC from the Power Supply Module to the DC striker output modules. | |||
The interface module features both a galvanically isolated, twisted pair wired interface to the control panel and an optional optical interface. | |||
