Page 4: Introduction
INTRODUCTION The NT240 programmable timer is used to monitor the time and trigger the output according to the program previously set by the user. It offers several pre-established operation modes. The only thing required is to define the time intervals to be used. It also allows you to create an operation mode. -
Page 5: Features
On terminals 7 and 8, the timer has an auxiliary voltage source (AUXILIARY SUPPLY OUTPUT) with 12 Vdc ±10 % (50 mA max.). It powers the electronic sensors applied to the device. The (-) terminal is common to the GND terminal of the inputs. This voltage source is not electrically isolated from the Digital Input circuits. NOVUS AUTOMATION 5/17... -
