Safety temperature limiter 0253-2001-23/005 - Temperature control relay AC 110...240V 701150/8-01... – Jumo – 00548736 – 4053877010401: Safety temperature limiter 0253-2001-23/005 701150/8-0100548736 Design of the electrical connection screw connection, rated control supply voltage Us at AC 50 Hz 110 ... 240V, rated control supply voltage Us at AC 60 Hz 110 ... 240V, type of voltage for Actuation AC, number of measuring circuits 2, error storage possible, number of contacts as NC contact 0, number of contacts as NO contact 0, number of contacts as changeover contact 2, temperature measuring range -200 ... 850°C, width 45mm, height 89.4mm, Depth 104.8mm, The configurable safety temperature limiter/monitor according to DIN EN 14597 with 1oo2D architecture is equipped with two universal analog inputs, two relay outputs (pre- and limit value alarm) and a universal analog output. The switching capacity of the relay contacts is AC 250 V, 3 A, 50 Hz (resistive load). The pre-alarm can be set as an absolute value or as a distance from the limit value. The front impresses with the brilliant LC display with background lighting and plain text display. With the use of the safety temperature limiter (STB) and safety temperature monitor (STW), dangers that can lead to injury to people, damage to the environment or the destruction of production systems and production goods can be detected and averted at an early stage. Its primary task is to reliably monitor thermal processes and to put the systems in a safe operating state in the event of a fault. The measured value at the analog input can be recorded using various sensors or standard signals. If a limit value is exceeded, this is signaled by the built-in LEDs for each channel and the alarm relay output switches the system to an operationally safe state (alarm range). The high requirements of DIN EN 61508 and DIN EN 13849 are met by a device concept whose 1oo2D structure ensures the reliable detection of errors and can therefore also be used in applications that are subject to the new Machinery Directive 2006/42/EG. When used as a safety temperature monitor STW (protective temperature monitor), the device works with automatic reset (e.g. for heat-generating systems). This takes place after the sensor temperature has fallen below the set limit value by the amount of the switching differential (setting: max alarm). The automatic reset occurs when the minimum alarm is set, after the sensor temperature has risen above the set limit value by the amount of the switching differential. When used as a safety temperature limiter STB (protective temperature limiter for heat-generating systems), the reset is done manually or with a tool. The power supply range is from AC 110 to 240 V +10% /-15%, 48 to 63 Hz.
