MODEL: HJPA–[1][2]–R[3]
ORDERING INFORMATION
• Code number: HJPA-[1][2]-R[3]
GENERAL SPECIFICATIONS
Construction: Plug-in
Specify a code from below for each of [1] through [3].
(e.g. HJPA-3A-R/Q)
Connection: M3.5 screw terminals (torque 0.8 N·m)
Screw terminal: Nickel-plated steel (standard) or stainless
steel
• 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.
• Specify the specification for option code /Q
(e.g. /C01/S01)
Housing material: Flame-resistant resin (black)
Isolation: Input to output 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
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.)
