Product Overview
The Emerson EMERSON 191736-01 is a robust rotary encoder designed for precise valve position feedback in industrial automation systems. This voltage rating module operates at 5 VDC with a flange mount and a 10-pin connector, part of the SCS-2/SDC50-2-7 series. It delivers reliable end-of-travel signals using mechanical or inductive contacts, ensuring accurate indication of valve stem positions. Built for harsh environments, it features an IP66 rating, durable glass fiber reinforced PA body, and stainless steel components. The encoder supports SIL2 applications per IEC 61508:2010, making it suitable for safety-critical processes.
Technical Specifications
The Emerson EMERSON 191736-01 offers key electrical and mechanical parameters derived from its datasheet:
-
Operating Voltage: 5 VDC (encoder); mechanical contacts handle 24 V AC/DC; inductive contacts (PNP/NPN) accept 10 to 30 V DC
-
Contact Ratings: Inductive contacts have a maximum wattage of 0.95 W; mechanical contacts break up to 0.5 A (max 1 A), inductive contacts up to 100 mA
-
Environmental Protection: IP66 per EN 60529, vibration resistance up to 1 g (EN 60068-2-6)
-
Temperature Range: -20°C to +80°C (mechanical contacts) or -20°C to +70°C (inductive contacts)
-
Construction Materials: Body in glass fiber filled PA, cover in PA or aluminum, valve adaptor in brass or stainless steel, stem/cams in stainless steel and PEEK
The encoder uses a flange mount with a 10-pin connection and a cable gland M16x1.5 accommodating 4–8 mm diameter cables. Electrical connection is via a 4-position terminal block accepting 0.14–2.5 mm² wire.
Industrial Applications
The Emerson EMERSON 191736-01 excels in valve position monitoring for oil and gas, chemical processing, and water treatment plants. Its SIL2 capability suits safety shutdown systems where reliable end-of-travel signals are critical. For example, in a pipeline control valve, the encoder detects full open/close positions and sends signals to a PLC or DCS, enabling automated control and preventing over-travel damage. The IP66 housing ensures performance in wet or dusty environments.
Installation and Setup
Mount the Emerson EMERSON 191736-01 directly to the valve actuator using the provided flange pattern. Connect the 10-pin encoder to the controller via shielded cable for noise immunity. Wire the terminal block for mechanical or inductive contacts per the wiring diagram: use 24 V AC/DC for mechanical contacts or 10–30 V DC for inductive contacts. Tighten the cable gland to secure the cable (4–8 mm diameter) and maintain IP66 seal. Avoid overtightening to prevent damage. Calibrate the cam positions at both travel limits to ensure accurate signal generation.
Maintenance and Reliability
The Emerson EMERSON 191736-01 is designed for long service life with minimal maintenance. Periodically inspect the cable gland and interface gasket for signs of wear to preserve IP66 protection. Clean the transparent cover (if PA) with a soft cloth to maintain visibility. Check that the cam and stem assembly moves freely. For inductive contacts, verify that the target material is compatible (steel). Given its robust construction and RoHS/REACH compliance, this part reduces downtime and replacement costs—a smart investment for continuous operations.
Selection Guide
Before purchasing the Emerson EMERSON 191736-01, confirm your valve actuator's mounting pattern and shaft type. Verify that your control system accepts 5 VDC encoder signals and either mechanical or inductive contact inputs. For SIL2 applications, ensure the integrated safety system meets IEC 61508 requirements. UBEST Automation (ubest101) stocks this genuine Emerson part, ready to ship.
