5.4 Alarm Output
The Datamate 2200 Coriolis Flow Transmitter provides two solid-state relays (SSR)
outputs for alarm outputs. These can be programmed for activation from measurement
values and system warnings. The SSRs are galvanically isolated to 3.75 Kv. The
maximum load voltage and currents are 230 VDC/AC and 100mADC/AC.
The SSRs function as switches to make or break power to the alarm devices. The SSR
outputs are not connected to a voltage source internally in the Datamate 2200. Figure
5.4.1 shows the connections for alarm devices that sense an open or closed contact.
For alarm devices that require a switched voltage, the user must make the connections
required to switch voltage to the alarm devices as shown in Figure 5.4.2.
