Type 3410 & Type 3420 Digital Circuit Card OEM Pressure Regulator

Brand: Marsh Bellofram Group of Companies

Type 3410 and Type 3420 Digital Circuit Card OEM Pressure Regulators from Bellofram PCD.

The compact Type 3410 (single-loop) and Type 3420 (double-loop) Circuit-Card Pressure Regulators are perfect for size-conscious OEM’s, without sacrificing any of the high-end performance normally associated with full-size I/P’s.

The T3400 is available with either of two user interfaces: the T3400S with serial interface or the T3400D with DeviceNet interface. The T3400D consists of the T3400S plus a sister board for DeviceNet functions.

The T3400 can be controlled digitally (via the serial or DeviceNet interfaces) or with industry-standard analog control signals (0-10 V or 4-20 mA). They are available with choice of either single loop or dual control loop, to suit various requirements.

Industry-standard analog monitor output signals (0-10 V or 4-20 mA optional) are available for user-monitoring of actual output pressure.

The small footprint of the Type 3410 and Type 3420 facilitate their ease of installation within space constrained environments, and are ideal for virtually any compatible industrial application.
