DPF20 Frequency, rate, total or period counter Instruction Manual
The R1, T1 and SSR modules provides 1 relay output, 1 transistor out-
put or 1 SSR drive output, to install in DPF20 digital panel meters, up
to a maximum of 3 modules in a single meter.
Note : for more than three relays per instrument or larger relay den-
sity per module, see special modules R2, R4 and R6.
Conguraon is performed from the frontal keypad of the meter,
by seng the parameters at the alarms conguraon menu (‘ALr.1’,
‘ALr.2’ or ‘ALr.3’ depending on the posion the module is installed).

The menu allows to congure the setpoint, hysteresis, independent
acvaon and deacvaon delays, and a second setpoint to create
alarm windows.
Modules R1, T1 and SSR are isolated against all other instrument cir-
cuits, and isolated between them.
Modules R1, T1 and SSR can be ordered pre-installed into a DPF20
digital panel meter, or standalone for delayed installaon, as they do
not require soldering or special conguraon.
