IC.PD.P10.M6.02 / 520B4852 Technical brochure Pressure controls, Type BCP Features y Available as high and low pressure limiters as well as pressure controllers y Wide pressure range: from low pressure BCP1 with narrow differential to high pressure BCP7 y The fail-safe dual bellows enable premature cut-out when fault occurs y DIN plug mounted on the top of control for easy electrical wiring y Single-pole changeover switch (SPDT), switch + alarm The BCP type is a series of dedicated pressure controls for safety and pressure monitoring of steam and hot water boilers. The BCP incorporates a single-pole changeover microswitch where the contact position depends on the pressure in the connection port and the range set value. For installations, in which operation is particularly critical for safety reason, the use of fail-safe control is recommended. y Direct mounting on pressure connection or wall mounting by means of a bracket y Versions with automatic and manual resets available y Screw adjustments made on top of housing y Manual reset for pressure limiters possible only by means of tools y Version with gold plated contact for electronic devices y Safety Integrity Level: SIL 2 according to IEC 61508:2010 MAKING MODERN LIVING POSSIBLE 2Technical brochure Pressure controls, type BCP IC.PD.P10.M6.02 / 520B4852 Approvals Materials in contact with media Bellows: stainless steel 1.436 (18/8) Pressure connection: nickel plated free cutting steel Technical data Media Steam, water, air Ambient temperature –20 to 70°C Media temperature Up to 120°C (Above 120?C a water-filled loop must be installed) Enclosure IP 65 Action type acc. to EN 60730 Type BCP - 2B Types BCPL/ BCPH - 2BDF Electrical connection Plug, DIN 43650, Pg 11 Switch type SPDT, snap action microswitches: type A and type B Contact material: Type A: Silver/ gold (Au plated Ag) Type B: Silver (AgCdO) Contact load BCP type A (silver/ gold contact) Minimum: 4mA, 5V Maximum: 1) 2)
