Parameter Options Default Description
Retentive
mode NO
YES NO Applicable for latched relays.
In non-retentive mode, the relay always
returns to its non-active state upon
power up.
In retentive mode, the relay status is
restored to what it was prior to loss of
power.
Pulse width 20-1000 ms 100 ms The actual pulse width is a multiple of
the 1/2-cycle time rounded to the
nearest bigger value.
The pause time between pulses is equal
to the pulse width.

NONE Links a pulse relay to the internal
energy pulse source. The relay must be
set into either pulse, or KYZ mode.
Pulse rate,

Generating Energy Pulses through Relay
Outputs
To generate energy pulses through a relay output:
1. Set a relay to either pulse, or KYZ mode, and then select
a polarity (active pulse edge) for energy pulses and a
pulse width.
2. Select a source accumulator (type of energy) and the
pulse rate for your output.
3. Store your new setup to the device.
Programming Analog Inputs
The PM175 can be provided with two optional analog inputs
with options for 0-1mA, ±1mA, 0-20mA or 4-20mA input
currents, depending on the order. The 0-1mA and ±1mA
inputs can accept 100% overload currents, i.e., can actually
measure currents in the range of 0-2 mA and ±2mA.
The meter automatically converts the analog input readings
received from the analog-to-digital converter to the user-
defined engineering scale and shows the input values in true
engineering units, for example, in volts, amps, degrees, with
the desired resolution.
To configure the Analog Inputs in your device, select General
Setup from the Meter Setup menu, then click on the Analog
Inputs tab. If you are programming your device online, analog
inputs are designated as not available if they are not present in
the device.
