Recommended Accessories

Radio Design Labs' ST-LCR3 is ideally suited to applications where momentary pulses are needed from a single control signal. The module provides a momentary pulse when a logic signal at its input first becomes active. A separate momentary pulse is provided when the logic signal at the module input becomes inactive.

Two logic inputs are available on the ST-LCR3. Either of these inputs may be used. Terminal 1 is internally pulled high to +5 Vdc. This input becomes active when an external closure or open-collector pulls the terminal to ground. The external switching device does not need to pull the terminal high, however the terminal may be pulled high with any voltage from +3.3 Vdc to +24 Vdc without any risk of damage to the ST-LCR3 input. Terminal 3 is internally pulled to ground. This input becomes active when an external closure or logic device applies a positive voltage from +3.3 Vdc to + 24 Vdc.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.

When the input being used first becomes active the START PULSE output from the module is triggered. When the input first becomes inactive (after first being active) the END PULSE output from the module is triggered. Both the start and end pulses have a nominal duration of 250 ms.

Each pulse output provides both an open-collector SLAVE terminal and relay contacts. The SLAVE terminal may be used to control other RDL modules and a variety of other equipment. The relay contacts may be used to control modules or equipment that do not operate from open-collector control.

Features:

  • Pulse at the Start of a Logic Signal
  • Pulse at the End of a Logic Signal
  • Relay Contact and Open-Collector Pulse
  • Active High or Active Low Inputs
  • Input Control Voltage From 3.3 to 24 Vdc
  • Control from Switch, Pushbutton, or Logic Circuits

Typical Performance:

  • Inputs (2): Logic High or Logic Low (Low = ground, High =3.3 Vdc to 24 Vdc) < /FONT >
  • Outputs (2): Open collector @ 25 mA suitable to drive indicators or slave LCRs.
  • Maximum Switching Power: 60 W (220 Vdc, 125 Vac, 2 A)
  • Power Requirement: GROUND-REFERENCED, 24 to 33 Vdc @ 100 mA (assuming 20 mA max load at SLAVE output)
