1. Electro Mechanical Relay Option DP3600 units can be ordered with either open collector outputs or electro mechanical relays Check model number printed on the unit for option If ordered with relays then these relays are programmed during Setup to operate as either Normally Open NO or Normally Closed NC The default setting is Normally Open Each of these limit relays provides a switched output whenever a limit is reached The maximum rating for a 120Vac unit is 120Vac 0 5 amp or 28 Vdc E 1 0 amp Figure 1 Electro mechanical Relays Hookup Example Instrument V OUTPUT CONNECTOR Y Switched Output LIMIT 4 E AE 130 VAGO UE AMPS p A Mel RO VACOOSAMPS LIMIT 3 Tl Ts 1 VACAS Switched Output E Y fa LIMIT 2 GN Switched Output 120 VAC 0 5 AMPS Y Mel l LIMIT 1 TTT Switched Output 20 VAC 0 5 AMPS na LIMIT RELAYS Open Collector Option Whenever a limit is reached an open collector output provides a 5 Vdc signal at 50ma on the output connector e g Limit 1 provides its 5 volt output signal between pins 1 and 2 Figure 2 Open Collector Hookup Example Instrument Solid State Relay LED Buzzer etc HOLD FUNCTION The hold function allows to freeze the Process Variable reading in the display window indefinitely till the Hold pin is active This function is activated by tying Hold pin pin13 to the digital ground pin pin 14 through a r2.
