Tacho Inputs
The DYN module includes two local tacho inputs, 0 and 1.
These inputs are not isolated from other module circuitry; the signal input has
a resistive pull-up to 5V and the return connection is analog ground/return.
These local inputs are designed for when one of the following is available:
• a TTL level tacho signal
• a tacho sensor with an open collector output (such as NPN type)
• a connection to an Opto output on another Dynamix module
• the TTL output from an XM-220 Dual Speed module (1440-SPD02-
01RB)
In most situations, the preferred method of providing tacho signals to the
module is through the TSC Expansion module.
