Page 2: General Description
General Description The Type 900 is a dual channel trip amplifier which accepts a signal from a vessel mounted sensor and operates individual relays anywhere over its input range. When in ‘run’ mode the 4 digit LCD gives a real time reading of the signal from the transmitter. - Page 3 Connection The Type 900 is available as a DC or AC version (factory set). The lower terminal block is for connection of the users power supply input to the product and the Type 900 volt free relay contacts outputs. The upper terminal is the connection to the input sensor.
- Page 4 Multi Type 900’s can be used for more demanding applications that require additional relay outputs by connecting the transmitter loop in series as follows. Programming the Type 900 On some models when initially powered the LCD may briefly display the software revision number.
- Page 5 The fail safe of the Type 900 is automatically determined by the relay set points. If the ON point is greater then the OFF point it is failsafe LOW, if the OFF point it is greater than the...

When mains AC is present the Type 900 operates from the DC output from the mains AC power supply, when the mains AC fails the Type 900 operates from the battery. It is essential to put a diode such as a IN4001 in series with each of the +V supplies to the 900, see diagram below.
