1056-01-22-38-AN | 1056 Dual-Channel Analyzer, pH/ORP + Conductivity, 4–20mA, NEMA 4X

1056-01-22-38-AN dual-input smart transmitter — Ch1: pH/ORP/ISE/DO, Ch2: Conductivity/Resistivity/Temp. 2×4–20mA, relays, backlit LCD, 100–240V AC, NEMA 4X / IP66.

Product Overview

1056-01-22-38-AN is a dual-input microprocessor-based smart analyzer/transmitter from 1056 series, designed for continuous online monitoring in municipal and industrial applications. It is factory-configured with Channel 1 = pH / ORP / ISE / Dissolved Oxygen (universal analog input) and Channel 2 = Conductivity / Resistivity / Temperature (2-electrode or 4-electrode probe compatible). The unit provides two isolated 4–20 mA outputs (one per channel), four programmable SPDT relay contacts for alarm or control, and a backlit alphanumeric LCD for local configuration and reading. Power is 100–240 V AC 50/60 Hz. The NEMA 4X / IP66 wall-mount or panel-mount enclosure suits washdown and outdoor panel locations. Compatible with 3900 / 396 / 398 pH sensors, 342 / 344 / 346 conductivity cells, and 499 DO probes.

Key Features

Dual Independent Channels: Monitor pH/ORP on one loop and Conductivity/Resistivity on another — eliminates need for two separate analyzers.
Universal Sensor Recognition (Ch1): Auto-configures for pH, ORP, ISE, or DO probe — simplifies spare stocking and commissioning.
Four Programmable Relays + 2×4–20 mA: Supports alarm, sample-wash timer, limit control, or failsafe actions — fully software-assignable.
One-Button Calibration with Prompted Menus: Step-by-step pH 2-/3-point, conductivity 1-point, DO air/zero calibration via front keypad.
NEMA 4X / IP66 Enclosure: Suitable for outdoor shelters, washdown areas, and corrosive plant atmospheres.

Typical Applications

Semiconductor / Pharma UPW: Conductivity/resistivity (Ch2) + pH/orp (Ch1) on ultrapure water loops.
Wastewater Treatment: pH control in neutralization basin (Ch1) + conductivity trend of influent/effluent (Ch2).
Cooling Tower / Boiler Feed: pH monitoring + blowdown conductivity control from a single analyzer.
Food & Beverage CIP: pH verification of caustic/acid wash + conductivity check of final rinse water.

1056 model decode: 1056 = Dual-channel analyzer | -01 = Ch1: pH/ORP/ISE/DO universal | -22 = Ch2: Conductivity/Resistivity/Temp | -38 = 100–240V AC power, 2×4–20mA, 4 relays, NEMA 4X, Eng/French display | -AN = No special agency (std.), ANSI/ISA term. strip. Sensors (e.g. 3900VP-01-10) and installation hardware ordered separately.
