Innovation First Spike Blue Relay Module Sep 2005 www ifirobotics com Guide Page 1 Notice This Manual covers the Spike Blue Not the Spike Red Spike is an H Bridge relay module custom designed for Robotics applications The most common use of Spike is to drive small motors in Forward Reverse or Off Spike can also be used to turn ON or OFF solenoids and lights Spike takes input power from a 12V battery labeled 12V GND and provides two outputs labeled M M M and M are typically connected to a motor The unit is controlled via a three wire interface which connects to the FRC Robot Controller or the Isacc16 Robot Controller Spike has a 20A integrated fuse to help protect the unit and it has an indicator to show status WARNING BEFORE APPLYING POWER 1 Ensure that there is not a short circuit on the output A short circuit will destroy Spike Figure 1 Spike Blue Wiring to One Motor Light or Solenoid Figure 2 Spike Blue Alternate Wiring for Two Solenoids PWM Relay Cable Motor Light or Solenoid 12V Battery FRC Robot Controller or Issac16 RC Relay Outputs 12V Battery Solenoid Solenoid Innovation First Spike Blue Relay Module Sep 2005 www ifirobotics com Guide Page 2 Notice This Manual covers the Spike Blue Not the Spike Red Motor and Solenoid Wiring The two motor connections can be wired to either of the relay outputs M and M are only labeled to i
3. ndicate the polarity of the output versus the control signal and Spike s indicator If your motor turns opposite of the direction desired swap the wires connected to M and M The 3 wire Control PWM cable contains a black wire for ground a red wire for reverse and a white wire for forward The table below shows the corresponding output versus the control signal and the indicator Table 1 Spike Blue P BASIC software control Spike output Motor function INPUTS OUTPUTS Fwd Wht Rev Red M M Indicator Motor Function 0 0 GND GND Orange OFF Brake Condition default 1 0 12v GND Green Motor rotates in one direction 0 1 GND 12v Red Motor rotates in opposite direction 1 1 12v 12v Off OFF Brake Condition Notes 1 Brake refers to the dynamic stopping of the motor due to the shorting of the motor inputs This condition is not optional when going to an off state 2 The INPUT Fwd and Rev are defined as follows 0 Off and 1 On One or Two Solenoid Wiring The Spike Relay Module can be used to control solenoids The easiest method of connection is to wire one side of the solenoid to M and the other wire to the ground GND side of the Battery When the relay is sent a Forward Indicator Green command the solenoid will be activated The same can be done with the M connector to control another solenoid or the opposite direction of a double solenoid see Figure 2 on page 1 Table 2 Spike Blue P BAS
