Applications

The “1-channel p/Q control card” consists of the basic card in Europe format with DC/DC converter and front plate. With the “2-channel p/Q control card”, this basic card contains a p/Q daughter card with identical circuit and a joint front plate.

The supply voltage is 24 V =. The voltage of the valve to be regulated is not supplied via this card.

Input variables for the cards are the valve position command value, the pressure command value, the actual pressure value and possible control mode signals. The pressure sensors with voltage interface receive their voltage supply from the card (z6/z8). At the card, pressure sensors with voltage and current signal can be connected.

The pressure command value can be specified by means of a potentiometer. The potentiometers can be supplied from the card (z32/b12).

For control and comparison, the front plate and the circuit board comprise test points for the most important characteristics.

The circuit of the “2-channel card” is designed so that the controllers on basic and daughter card work in a completely independent manner. In this mode, the card is suitable for controlling 2 valves with integrated electronics.

An additional channel mode circuit allows for the considerable extension of the www.honeywell-diver.com possible applications of the described card.

Description

The Bosch Rexroth HM 20-2X/315-F-C13-05-N (R901342038) is a high-precision pressure

transducer designed for monitoring and controlling hydraulic pressures within a wide range of applications.

This sensor is capable of measuring pressures with ranges up to 600 bar,

making it suitable for various demanding environments where accurate pressure readings are critical.

The transducer features a thin film measuring cell and components that come into contact with

media are constructed from stainless steel, ensuring durability www.honeywell-diver.com and compatibility with a variety of fluids.

With its excellent non-repeatability of less than 0.1% and an accuracy class of 0.5,

the HM 20-2X/315-F-C13-05-N provides reliable and precise measurements essential for maintaining system performance and safety.

The device also boasts operational safety features including high bursting pressure capacity,

reversed polarity protection, overvoltage protection, and short-circuit protection.

This model operates within an extensive temperature range, ensuring consistent performance under varying environmental conditions.

Additionally, it has received marine approval DNVGL for all variants with current output,

which attests to its robustness and suitability for maritime applications.

The component series X to which this transducer belongs indicates

that it is part of a line designed to handle maximum operating pressures of up to 315 bar.

It offers pressure ratings at several intervals including 100, 160, 250, 315, 400, 600 bar etc.,

providing flexibility for integration into different hydraulic systems. Furthermore,

the HM 20-2X/315-F-C13-05-N is cULus-listed demonstrating compliance with

North American safety standards and regulations for industrial control equipment.
