3.9 Output Functions
3.9.1 General
The following table describes the electronic output functions the MSC-L
supports.
3.9.2 Pulse Output (PO DC)
3.9.2.1 Functional Description
The Pulse Output DC (PO DC) allows the controller to switch DC
signals to interface a PLC, TAS, or other systems. The PO is not
designed to switch the high-current loads.
The two output terminals behave as “volt-free” contacts and require an
external power supply to drive a load.
Real-time PO circuitry contains a multiplexer and a selector, which is
controlled by a micro controller to select certain pulse input circuitry to
the pulse output channel.
Factored PO circuitry is controlled by a micro controller to present a
certain pulse input signal factored (scaled) to the pulse output channel.
FIGURE 3-31 illustrates the simplified block diagram of the external PO
connections.
