Microprocessor based sixteen-channel scanner/data logger from libratherm instruments is ideal for constant monitoring of temperature/humidity/process variables at 16 different locations. Sixteen independent inputs are accepted by the data logger. It is very cost effective because it does not require individual temperature/process indicators. It is available for 4, 8, 12 and 16 channels in the 1/2 din size of [192 x 96 x 200] mm. There are 4 separate displays, which show the process value, set value, channel number simultaneously. There is also a 6-digit display for real time clock and calendar. Standard features include scan/hold facility, independent alarm levels per channel which can be configured for low alarm, high alarm or very high alarm in normal or in latch mode with acknowledge or reset facility as per the users; requirement, status of alarm indication on the front panel by means of leds, common high and low alarm relays, 32 independent open collector transistor drivers, [4-20] ma re-transmission output per channel, etc., makes the instrument very versatile and user friendly.
