GENERAL METER SPECIFICATIONS
Note:
The
PM-50 4.3 inch host accepts a maximum of 5
modules while the 3.5 inch host accepts a maximum of 3.
Only one module from each function type (i.e. communication,
relay, analog output) can be installed.

SIGNAL INPUTS (INPUT A and INPUT B)
:
Software configurable input types including switch contacts,
TTL outputs, magnetic pickups and all standard RLC
sensors. Inputs are configurable for current sinking or
current sourcing outputs with input filtering for low
frequency signals or switch contact debounce. Not isolated
from the sensor input common.
Logic: Input trigger levels V
IL
= 1.2 V max.; V
IH
= 3.75 V min.
Sink: Adds internal 7.8 KΩ pull-up resistor to +5 VDC, 0.7
mA max
Source: Adds internal 3.9 KΩ pull-down resistor, 7.3 mA
max. at 28 VDC, V
MAX
= 30 VDC
Magnetic Pickup:

Dual Count Modes:
When any dual count mode is used, then User Inputs 1 and/
or 2 will accept the second signal of each signal pair. The user
inputs do not have the Logic/Mag, HI/LO Freq, and Sink/
Source software selections. The user inputs are inherently a
logic input with no low frequency filtering implemented in
software. The user input may only be selected for sink/
source by the User Input Active parameter.
