Product description
Siemens 3TK2827-1BB41 is a safety relay from the SIRIUS 3TK28 product series. The device uses a 24 V DC control supply and screw terminals. Its enabling circuits comprise two instantaneous NO contacts and two delayed NO contacts. One NC signalling contact is also documented. Switch-off delay for the delayed circuits is adjustable from 0.05 to 3 s. The instantaneous safety circuits are rated SIL3 and Performance Level PL e, while the delayed circuits are rated SIL2 and PL d. The start function is monitored. Input wiring can be single- or dual-channel. Maximum thermal contact current is 5 A. The enclosure and terminals have IP20 degree of protection. Manufacturer data state a width of 44.8 mm, height of 138.5 mm and depth of 120 mm. Complete overall dimensions are therefore 44.8 × 138.5 × 120 mm in width, height and depth order. Net weight for the exact order number is 0.457 kg. Dimensions and weight refer to the individual basic device without packaging or additional accessories. Mechanical data distinguish this exact version from other relay variants with a similar front view. Electrical assignment depends on control supply, contact arrangement, delay range, start function and terminal type. Identifier 3TK2827-1BB41 designates the 24-V-DC version with screw terminals and monitored start. Other order numbers in the 3TK28 family can use different voltages, delay ranges or terminal technologies. The documented dimensions define the installation envelope on the mounting rail, while net weight adds data for storage and transport. All technical values, dimensions and weight are assigned to this specific device variant.
