and at the Standard Rack connector

RELATED PRODUCTS

• Programming Unit (model: PU-2x)

• PC configurator software (model: JXCON)

Downloadable at M-System’s web site.

A dedicated cable is required to connect the module to the

PC. Please refer to the internet software download site or

the users manual for the PC configurator for applicable

cable types.

Typical Applications

• Positive displacement flowmeters, turbine flowmeters and

vortex flowmeters

• Proximity switches

• Oval flowmeters

GENERAL SPECIFICATIONS

Construction: Rack-mounted; terminal access via screw

terminals on the front and connector on the rear; terminal

cover provided

Connection

Input: M3.5 screw terminals (torque 0.8 N·m)

Output 1: Connector

Output 2: M3.5 screw terminals (torque 0.8 N·m)

and connector

MODEL: 18JPA–[1]66–R

Power input: Supplied from connector

Screw terminal: Nickel-plated steel

ORDERING INFORMATION

• Code number: 18JPA-[1]66-R

Isolation: Input to output 1 to output 2 to power

Overrange output: -10 – +120 % at 1 – 5 V

(0 – 120 % when 0 % input equals to 0 Hz.)

Linearization: 16 points max. represented as percentage of

full-scale

Specify a code from below for [1].

(e.g. 18JPA-266-R)

• Frequency range (e.g. 0 – 152.3 Hz)

• Linearization data (max. 16 points)

Use Ordering Information Sheet (No. ESU-1673) to specify

linearization data when the I/O signals are non-linear.

Note: Consult factory on applications with a sensor handling

periodically (& quickly) changing frequency (e.g. oval

flowmeter).

Adjustments: Programming Unit (model: PU-2x); input

range, low-end cutout, zero and span, simulating output,

averaging nonuniform pulses, linearization data, etc.

(Refer to the users manual of JXCON for the adjustments

configurable with JXCON.)

Low-end cutout: 0 – 100 % adjustable (factory set to 0 %);

hysteresis fixed to 1 %
