GENERAL SPECIFICATIONS
Construction: Rack-mounted; terminal access via screw
terminals on the front and connector on the rear; terminal
cover provided
MODEL: 18KJPA–[1]66–R[2]
ORDERING INFORMATION
• Code number: 18KJPA-[1]66-R[2]
Connection
Input: M3.5 screw terminals (torque 0.8 N·m)
and connector
Specify a code from below for each [1] and [2].
(e.g. 18KJPA-266-R/S)
Output 1: Connector
• Frequency range (e.g. 0 – 152.3 Hz)
• Linearization data (max. 16 points)
Output 2: M3.5 screw terminals (torque 0.8 N·m)
and connector
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).
Power input: Supplied from connector
Screw terminal: Nickel-plated steel
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
[1] INPUT
1: Open collector (Excitation: 12 V @ 30 mA)
2: Voltage pulse (Excitation: 12 V @ 30 mA)
3: Mechanical contact (Excitation: 12 V @ 30 mA)
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.)
OUTPUT 1
